hello, I am planning on switching to 32" tires and am wondering what the xcal can do to help...i know it can tell the engine that the tires are bigger and what not but what will it do to give the truck more power, and will this be noticeable

 

You'll notice the difference, sure. But if you're really looking just to compensate for whatever power loss due to the bigger tires, cheaper than the X-Cal 2 is to re-gear.

 

my gears are currently 3.73 so to regear would i just need the 4.10 ring and pinion set?

 

yup

 

Or 4:56's
